Wonderful math tool...the double side is especially helpful for my youngster who needs this for understanding place value
Super Great math learning tool
Pathetic App froze and wouldn't work, also no instructions on how to use the abacus
Homeschool mommy Love it. I have the actual albicus and the app on my iPad as well as my phone.
Does not work on my device.
Fixed a bug where the app would not start on 2.x devices
